Lines of chrysanthemum

Do lines need to be straight? I was pondering about this question all day, considering what to post today. Do the petal of this chrysanthemum form a line pattern? I think they do.

I found this image searching for something fitting this #MacroMonday theme of Lines. This image is all about pattern and shape, thus black and white treatment, which at the same time lacked… something. I decided to add color, not unlike original, by classic Split Toning.
